Fibre optic cable Synergy 21 S217049 20 m 2x LC OS2 Blue White Yellow

The Synergy 21 S217049 20 m fibre optic cable is a single-mode OS2 patch cable with two LC connectors configured for full duplex operation. Designed for high-speed data transfer, this 9 µm core cable provides low attenuation over longer distances compared with multimode alternatives. The cable comes with distinctive blue and white/yellow coloring to aid identification in racks and patch panels, and is intended for indoor network interconnections, patching and backbone links where single-mode performance is required.

Advantages

This LC to LC OS2 cable offers stable single-mode transmission with low insertion loss and reduced modal dispersion due to its 9 µm core. The 20 m length enables flexible routing between equipment in data centers, server rooms and telecommunications closets without additional splicing. Standard LC connectors ensure broad compatibility with network equipment that accepts LC terminations, while the color-coded jacket simplifies cable management and identification in multi-cable installations.

Suitable for

• Single-mode patching between switches, transceivers and patch panels
• Data centre and server room horizontal and vertical cabling runs
• Telecommunications closets and backbone links requiring OS2 performance
• Connections to SFP/SFP+ transceivers with LC ports

Key specifications

• Fibre type: single-mode OS2
• Number of fibres: 2 (full duplex)
• Connector type: LC to LC
• Core diameter: 9 µm
• Cable length: 20 m
• Jacket colors: blue with white/yellow markings
• Application: indoor patching and backbone connections

How to use

Inspect connector endfaces for cleanliness and remove protective caps before insertion. Route the cable avoiding sharp bends and excessive tension; maintain the minimum bend radius recommended for single-mode fibre to prevent microbending losses. Insert LC connectors into corresponding LC ports on equipment or patch panels until a secure click is felt. For duplex links, ensure correct alignment of transmit and receive ports. When disconnecting, depress the LC latch gently and pull the connector straight out to avoid damaging the ferrule.

Usage recommendations

Use a fibre inspection scope and approved cleaning tools to verify and clean connector endfaces before each connection. Secure cables with appropriate cable management to prevent strain and label both ends to simplify future maintenance. For long-term installations, store spare cable runs coiled without tight loops and avoid exposure to direct sunlight or fluids.
